Application filed August 14,1919. Serial No. 317,462.

To aZZ whom it may concern;

Be it known that I, 'J' snrrr Asa TON, a citizen of the United States, residing at Henderson, in the county of Henderson and State of Kentucky, have invented a new and useful Trolley- Construction for Barbers: Electrical Equipment, of which the following is a specification. i

This invention has reference to trolley construction for barbers electrical equipment,-a'nd its object is to'provide means whereby electrical current may besupplled to anyone of numerous chairs or stations in a barber shop without the necessity of uncoupling, and "recoupling the equipment every time that its service is needed.

In accordance with the invention, current is fed through two superposed overhead conductors ata suitable height to be out of the way and the conductors support a carriage capable of traveling thereon along a line of barbers chairs. riage is arranged, to support suchmecha nisin as is usually employed in electrically driven barbers equipment with-the latter in pendent relation to the carriage so that as foccasion requires the equipment may be moved to the desired chair ready for use without any plugging in, which latterop oration is the customary practice.

The invention will be. best understood from a consideration of following detailed description taken in connection with the accompanying drawing forming part of this specificationpwith the understanding, however, that the invention is not confined to any strict conformity 'with the show ng of the drawing, but may be changedand modified so long as such changes and modi fications mark no material departure from the salient features of the invention asexpressed in the appended claims.

In the drawing i y Figure 1 is, an elevation of the trolley structure as viewed from one face.

Fig. 2 is an elevation of the samestruc-l ture as viewed fromthe opposite face. Fig. is a plan view of the structure shown in Figs. 1 and 2. i Fig. 4: is a section on the line 4- 1 of Fig. 1. I p V Referring to the drawlng, there are shown-two conductors 1, 2, which maybe considered as bare conductors arrangedat a suitable height in substantiallyparallel relation and as connected with a suit- The car- 7 ably insulated conductors ablesource of current. The conductors 1 and 2 are tobe' understood as extended along a line of barber chairs in a barber shop. Adapted to run along the track formed by the two conductors 1 and 2 is a body member 3 which may be of elongated conformation and so -arranged as to'span the distance between thetwo conductors 1 and 2 and at the same time extend lengthwise ofthe track. The body member 3 is or may be made of some suitable insulating material. Wood will answer for the body member3 if the voltage of the current employed be suiiiciently low, or the body member 3may-be made of hardrubber orfiber, or insulation may be employed wherever found desirable.

' Near opposite ends of the bodymember 3 trolley wheels at and 5 are mounted. Each wheel, which may be-of good conducting material such as brass, 1s mounted on a spindle or arbor 6 traversing the body 3 and held by a nut 7. Eachroll'ert and 5 is 1 provided with a peripheral groove 8 to run upon a respective conductorl or 2 as the case maybe. Carried by the body member 3 adjacent to each roller 4 and 5 is another roller 9, which may be of insulating material, and each roller9 is mounted on an arbor or spindle 10 traversing the block 3 and heldin place by a nut 11. The roller 9 is" sci-situated as to underrun a respective conductor 1 or 2 as the case may be, and prevent escape otthe'roller i or 5 from the trolley wire 1 or 2. Adjacent to the meeting parts of a wheel 4 ore andthe roller 9 associated therewith, is an eye or guide 12 on the body member 3. 1

One face of. he body member 8 has a groove 13 formed therein, the groove being so situated as to extend up and down when the body 3 is properly located on the track formed by the two conductors or trolley wires 1'and2. Seated in the groove 13 is a tube 14: servingas'a support for barbers electrical equipment of any suitable character,'which equipment is therefore not shown 'forit may be of well known construction. The tube 14 also serves as a conduit for electrical conductors each connected to a respective arbor 6 of the wheels 41- and 5, the conductors 15 being held to the arbors by the nuts 7.' To retain the tube 14. in position on the body member 3 there is provided a clamping strap 16 made fast to the 15 which may be suit disconnection of a current.

body member 3 by bolts 17 having wing nuts 18 for ready manipulation so that if f it be desirable at any time to change the equipment suchvchange may be performed without the necessity of skilled labor.
